Weed control help (mixing 2,4D) *pics included*

My neighbor let me use his 2,4 D to poison today but I'm not sure on mixing ratios and don't wanna kill my entire yard. He told me to put 2 cups per 4 gallons. According to this, is calls for way less. WWTOBD??

In my landscape days, we never used it for weed control. We used it to kill saplings on fence lines.

Where can you buy that? I need some. I've always heard to mix it with Roundup for best killing results. I have some ridiculous weeds around my house that the Roundup doesn't kill dead enough.

1.5 or 2 oz per gallon is what almost all herbicides are made to be mixed at (at least the ones i use). Mixing extra will not kill more shite, just increase chemical runnoff and waste money. Once you hit either 1.5 or 2oz per gallon (depending on chemical) it has reached its minimum ratio for maximum effectiveness. 2-4D only kills broadleaf plants, so it is safe to use on your yard. It wont hurt regular grass.
Eta: if it doesnt have a surfactant in it, adding some liquid soap will help it stick to oily plant leaves. Some concentrates come with a surfactant. It should say somewhere on the msds.

My buddy gets me 2 4D also. What he gives me is in a different container. I mix it 1 to 1.5 ozs a gallon and spray my entire yard. Get some dye from one of the Nurseries so you can see where you miss. Mix a little dawn soap or Horticulture Oil with the mixture to make sure it sticks to the weeds. I will turn your grass brown but it will come back.

2,4-D is normally applied at 1quart per acre or 3/4 oz per 1000 sq feet
As a general rule a hand or backpack sprayer will apply 1 gallon per 1000sq feet, so for a 3 gallon sprayer use about 3-4 oz for applying in a yard. If you are spraying fence rows or saplings I would mix at double that rate.

We put 20 gallons of 2 4 D and 14 gallons of roundup into 800 gallons of water when we burn down on the farm. I don't have a calculator on me, but it should be easy to convert that to whatever size tank you have if you know your measurements.

Remember that all of the less concentrated ratios are for big sprayers that need to put a bunch of volume out to work well. When using a small hand sprayer, it's the difference between just putting a quick spray on the weed, or soaking it. The more concentrated, the less you have to use to put the same amount out. And the less total spray, the less likely you will kill something you don't want to.
Here's the math, 1.1-1.5 oz / .5-5 gal. So for a 4 gallon sprayer at 1.5 oz/.5 gal, you are at 12 oz. The neighbor said 16 oz (2 cups). Pretty close. Or, as I was taught, 2 sloshes of 2,4 D, and a half slosh of surfactant, fill up with water and go.

Got some of it and some industrial strength Round-up. Was told by a very knowledgable friend to mix an ounce of each per gallon of water. Shite works.
